4.11 kernel results (with CentOS 7.4 glibc):
https://gcc.gnu.org/ml/gcc-testresults/2017-07/msg00998.html

4.4 kernel results (with ubuntu 1604 glibc):
https://gcc.gnu.org/ml/gcc-testresults/2017-07/msg01009.html

Note the glibc does not matter here as I get a similar testsuite
results as the CentOS 7.4 glibc using the Ubuntu 1604 glibc but with
the 4.11 kernel.

Also note I get a similar results with a plain 4.11 kernel compared to
the above kernel.

Thanks,
Andrew
